The Z4-Forum has been going since July 2007 and has grown from a base of less than 10 to over 15,000, with more than 1 Million posts. The success of the forum is down to the participation of the community and the work of the moderators.

With the growth of the forum there are significant overheads in terms of hardware infrastructure, backups and maintenance. While some of this is supported by adverts it is always appreciated when members donate to the forum.
